SPECIFICATION forming part of Letters Patent N o. 665,088, dated January 1, 1901.

Application filed March 5, 1900. serial llo. 7,369. (No model.) i i l To all whom it may concern:

Be it known that I, JAMES GOULD, Jr. a citilzen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented new and useful Improvements in Can-Body Machines, of which the following is a specification. s

This invention relates to can-body machines which shape the bodies oftin cans and solder the seams of the same. -In the operation of these machines the blanks are fed successively by the operator upon a primary conveyer, which carries each blank step by step past the shaping mechanism, whereby the blank is bent into cylindrical form and the ends of the same are secured together by an interlocking joint, forming a double seam. After the can-body has been thus formed th'e same is delivered to a secondary conveyer, which .moves the same past the soldering mechanism, whereby the4 seam of the canbody is soldered.

The objects of this invention are to provide a simple and reliable fiuxing device whereby liquid flux is applied uniformly to the edges of the blank, which are seamed and soldered together; to improve the construction of the mechanism whereby the blank is bent intocylindrical form and its hooks are interlocked; to provide a drive mechanism for the conveyer which causes the conveyer to move intermittently forward to feed the blank to the forming mechanism and backs up slightly after each forward movement, so that the conveyer clears the blank and does not interfere with the forming operation; to provide a soldering mechanism which applies the solder uniformly to the seam of the can-body; to improve the construction of the wiping device whereby the surplus solder is removed from the seams of the cans, and to provide means which permit the secondary conveyer, which carries the can-bodies past the soldering mechanism, to be operated by hand independent of the can-shaping mechanism when the latter is clogged, thereby preventing the can-bodies from being injured by the heat of the soldering-steel.

In the accompanying drawings, consisting of nine sheets, Figure 1 is a side elevation of the front or can-shaping part of the machine. Fig. 2 is a side elevation, partly in section, of

fthe forming mechanism whereby the blank is bent into cylindrical form. Fig. 3 is a vertical longitudinal section ofthe frontparl of the machine.

Like letters of reference refer to like parts in the several iigures.

A represents the main frame of the machine, which may be of any suitable construction to support the different working parts of the machine.

B B represent a pair of endless chain belts which constitute the primary conveyer, whereby the blanks are carried successively past the fluxing, folding, and forming devices. These belts are separated by an intervening space and pass with their receiving and delivery portions around receiving and delivery sprocket-wheels b h, which are secured to transverse shafts b2 b3, respectively. The upper operative portions of the conveyerbelts run over horizontal rails b4, which are secured lengthwise to the frame. Each of the belts is provided at suitable intervals with primary feed wings or fingers h5, the wings of both belts being arranged transversely in line so as to form pairs.

While the fluxing and folding devices are operating upon a blank the latter is supported upona feed-table consisting of a central section C and two side sections C C2, the several sections being flush with the top of the operative part of the belts. The central section of the feed-table is arranged lengthwise between the conveyer-belts, and the side sections are arranged lengthwise on the outer side of the operative parts of the belts. 'Phe outer sections of the feed-table are provided with longitudinal side iianges or guides c, which are engaged by the side edges of the blanks and whereby the latter are held in place on the feed-table Iand belts. The central sect-ion of the feed-table is rigidly secured to the frame, but the side sections and side guides are capable of transverse adjustment thereon to adapt the machine to different widths of blanks for making cans of different diameters.

D D represent two iiuXing-wheels, of felt, leather, or similar material, whereby a coating of liquid flux is applied to the side edges of th'e blanks of sheet-tin as the same are carried forward by the belts toward the shaping mechanism. These wheels are arranged vertically near the front end of the operative portion of the belts and are adapted to bear with their lower portions against the upper side ofthe blank, along the side edges thereof, as shown in Fig. 4. Each of the fiuxiugwheels is pivoted transversely to an 4overhanging bracket CZ, which is adjustably secured to a transverse bar d, so as to permit of raising and lowering the fiuXing-wheel or moving the same inwardly or outwardly for adapting the IluXing-wheels to different sizes of blanks. The means for effecting this adjustment shown in the drawings consists of a clamping-bolt d2, passing through a vertical slot in the bracket and a horizontal slot in the cross-bar CZ. The liquid iux is supplied to the fluXing-wheels from reservoirs (Z3, each of which is supported on the bracket of its respective iiuxing-wheel and has the outlet nipple or nozzle on its bottom arranged to deliver the flux on top of the iiuxing-wheel. As the blanks of tin are moved forwardly by the primary conveyer-belts the side edges of the blanks are moved in contact with the lower part of the fluXing-wheels, whereby the latter are turned and carry the uX against the edges of the blanks. This construction of the Iiuxing device causes the flux to be applied uniformly and insures coating the entire side margins of the blank. The transverse bar d may be supported in any suitable manner, preferably by means of bolts CZ", passing through transverse slots in the bar, as shown in Fig. and entering screw-threaded openings in the tops of the side guides c, which construction permits the latter to be adjusted with reference to the cross-bar cl'.

After the flux has been applied to the blank the latter is moved forward one space and presented to a folding mechanism, whereby the side edges of the blank are folded preparatory to being interlocked and seamed. This folding mechanism is best shown in Figs. l, 3, 5, 8, and 13 to l5 and is constructed as follows:

E E represent a pair of coperati ng lower and upper clamping-jaws which are arranged below and above, respectively, the left portion of the blank when the latter comes to rest at the folding mechanism. The lower clamping-jawE is arranged to support the blank on its under side near its left-side edge and is provided on its upper side with a longitudinal channel or groove c, which is concave in cross-section, and on its outer longitudinal side with a bevel-face e, which inclines inwardly from the upper side of this jaw to the lower side thereof, as shown in Figs. 13110 l5. The jaw E is mounted on a transversely-adjustable carriage E2. The upper clampingjaw E is arranged above the path of the blank and is provided on its underside with a con- Vex face e2, which is adapted to cooperate with the concave face e of the lower jaw E.

While the blank is being fed to the folding mechanism the clamping-jaws E E' and adjacent parts are in the position shown in Fig. 13. After the blank comes to rest at the folding mechanism the upperjawl' moves downwardly toward the lowerjaw, whereby a downwardly-curved bend e3 is formed lengthwise in that portion of the blank between the jaws, as shown in Fig. l5, which bend facilitates the interlocking of the folds or hooks of the blank, as will be hereinafter described. The upper jaw is provided at its upper end with an outwardly -projecting bifurcated arm which is pivoted at its outer ends by longitudinal pivots to the carriage E2, as shown in IOO IIO

Fig. 8, so that the inner end of the arm turns in a vertical plane and raises and lowers the upper jaw E.

F represents a folding blade or jaw forming part of the mechanism whereby aiiange or hook is formed on the left end of the blank. This jaw is movably arranged above the left end of the blank when the same rests at the folding mechanism and is provided with a dat lower face f and a beveled inner face f', whichinclines from the lower side of the jaw to the upper side thereof. The folding-jaw is capable of both a downward-and-upward and an inward-and-outward movement. After the left edge of the blank has been clamped between the clamping-jaws E E the foldingjaw F rst moves its lower face fdownwardly against the end of the blank and bends the same downwardly over the outer edge of the lower clamping-jaw E, forming a dange on the blank, which is arranged at right angles to the body, as shown in Fig. 14. After this flange has been thus bent on the left end of the blank the folding-jaw is moved inwardly a short distance while in engagement with Athe flange, whereby the latter is bent inwardly at an angle between the bevel-faces of the folding-jawand lower clamping-jawand forms a downwardly and inwardly projecting hook on this end of the blank, as represented in Fig. 15. The folding-jaw now moves outwardly from underneath the lower jaw and then moves upwardlytogether with the upper jaw E', so as to clear` the blank.

f2 represents a side guide or gage which is arranged on the inner end of the folding-jaw and with which the left edge of the blank is adapted to engage for the purpose of centering the same when it reaches the folding mechanism.

The upward-an-d-downward movement of the folding-jaw is effected by a connectingrod f3, which is pivoted at its lower end to the upper side of the folding-jaw F and at its upper end to a vertically-reciprocating slide f4, which is guided on a standard G, rising from the main frame. This slide is raised and lowered bya cam f5, which is secured to a horizontal shaft g, journaled transversely in bearings on the upper end of the standard and which is provided with a cam-groove receiving a roller or projection on the slide f4. The downward movement of the upper clamping-jaw E takes place about the same time as thedownward movement of the folding-jaw and is effected by a connecting-rod g', pivoted at its lower end to the upper clamping-jaw E and at its upper end to a vertically reciprocating slide g2, which is guided on the standard G. This slide is depressed by a cam g2, arranged on the shaft g and engaging with a roller or projection on the upper end of the slide g2. The upper clamping-jaw E', together with the rod g and slide g2, are raised by the folding-jaw F, which latter during its upward movement engages with its upper side against the lower end of an adj usting-screw g4, arranged on the arm of the upper jaw. By this means the folding-jaw and upper jaw are raised together, but the folding-jaw is permitted to move laterally independent of the jaw. The foldingjaw F is pivoted at its outer end to a Vtransversely-movable slide H, which is guided in a way on the top of the supporting-carriage E2. This slide is reciprocated by an elbowlever h, which is pivoted on the carriage E2 and connected with its lower arm to the slide H, while its upper arm is connected with a vertically-reciprocating slideph by a connecting-rod h2. The slide h is guided in a way on the upper part of the standard G and is raised and lowered by a cam h2, which is secured to the shaft g and which is provided with a cam-groove receiving a pin or roller on the slide h. The cam h2 is so constructed that it moves the slide h' inwardly positively,

but permits the outward vmovement of the same to be shifted for adjusting the foldingjaw properly to the edge of the blank to produce the desired width of hook or flange on the same. The means for adjusting the outward'movement of the slide H shown in the drawings consists of a lhorizontal adjustingscrew h4, arranged in a depending lug on the slide H and engaging with a shoulder formed on the carriage E2. The slide H is yieldingly held in its outermost position by a spring h5 Y bearing with one end against a depending lug on the slide H and an adjusting-screw arranged on the carriage E2. When it is desired to form seam flanges or hooks on blanks of different widths for producing cans of different diameters, the carriage E2 is adjusted transversely on the frame, so as to bring the folding device mounted thereon into the proper posit-ion with reference to the edge of the blank which is operated upon. This adjustment may be effected by any suitable means, but preferably the means shown in the drawings, Figs. 13 to 15, consisting of a horizontal ad j usting-screw h6,journaled transversely in the main frame and engaging with IOO IIO

a threaded opening in the carriage E2. Upon so arranged that the blank rests with its rightv end upon the same when the blank comes to rest at the folding mechanism. This jaw is provided ywith an upper flat face t', which is normally iiush with the top of the feed-table and belt, and an inner beveled-face i', which inclines from the upper side of the jaw to the lower side thereof, as represented in Figs. 13 to 15. The folding-jaw I is guided in horiside of the upper clamping-jaw.

zontal ways on a transversely-adjustablc carriage I.

t2 represents a side guide or gage which is arranged on the right folding-jaw above its dat upper face and with which the right edge of the blank is adapted to engage for the purpose of centering the same when it reaches the folding mechanism.

J J represent the upper and lower jaws of a clamp which forms part of the mechanism whereby the upwardly-projecting seam hook or flange is formed on the right-hand end of the blank. The lower` clamping-jaw J is arranged below the blank when the latter is in a position to be folded and supports the same on its under side near its right edge, as shown in Fig. 13. The lower clamping-jaw is yieldingly supported, so as to permit the same to descend when the blank is pressed downward upon the same by the upper clamping-jaw J. As showin in Figs. 13 to l5, the lower clamping-jaw is movably mounted on the carriage I', the jaw being guided on the carriage by an upright guide-lug j, formed on the carriage I' and engaging with a recess in the under side of the lower clamping-jaw J. The latter is yieldingly held in an elevated position by a spring j', arranged in said recess and bearing with its ends against the lowerjaw J and the iiangej of the carriage. The upward movement ol' the lower clamping-jaw is arrested by a stop, so that the upper horizontal face or top of this jaw is normally Iiush with the top of the feed-table and the operative part of the conveyer-beltsr1`he stop for this purpose shown in the drawings consists of a transverse pin jg, secured to the lower clamping-jaw and adapted to engage with the upper end of a vertical slot in the angej of the carriage I' when the lower jaw is in its highest position. The upper clamping-jaw J is arranged above the path of the blank in line with the lower clamping-jaw J and is provided on its under side with a flat face and on its outer side with a beveled face 7'3, which inclines inwardly from the lower This jaw has an upward-and-down ward movement and also an inward and outward movement. Vhile the blank is being fed to the folding mechanism the folding-jaw I is in its outermost position, the lower clamping-jaw J is in its uppermostposition, and the upper clamping-jaw J is raised and moved into its outermost position, as shown in Fig. 13. After the blank has been fed to the folding mechanism the upper clamping-jaw is depressed, so as to clamp the blank against the lower jaw and also depress the blank and lower jaw. The right end of the blank rests on the right-hand folding-jaw while the adjacent inner part of the blank is thus depressed, whereby the outer end of the blank is turned upwardly into a iiange which is arranged at right angles to the body, as represented in Fig. 14C. While the upper and lower clamping-jaws are still in this depressed position the folding-jaw I moves inwardly, whereby the inner beveled face of this jaw presses the fiange on the blank against the beveled face of the upper clamping-j aw and forms the flange on the blank into an inwardly-projecting hook, as represented in Fig. 15. After this hook has been thus formed the foldingzjaw I moves outwardly away from the seam-hook into its retracted position, and the upper clamping-jaw J iirst moves inwardly from underneath the seamhook, as represented by dotted lines in Fig. 15, and then upwardly until it reaches the position shown by dotted lines in Fig. 13. During the upward movement of the clampingjaw J the lower clamping-jaw J' is also raised by its spring to its highest position, whereby this end of the blank is raisedflush with the top of the feed-table and belt. Preparatory to beginning the next downward stroke the upper clamping-jaw is moved outwardly into the position shown in Fig. 13. The upper clamping-jaw J is pivoted at its upper end to a vertically-movable slide 7c. The latter is guided in ways on the upper part of a standard 7; on the carriage I. The outward movement of the upper clamping-jaw is limited by a stop 7a2, which is preferably formed by the adjacent part of the carriage I', and the inward movement of this jaw is limited by a stop 7c3, which preferably consists of an adjustingscrew mounted on a bracket connected with the standard 7.5.

7a4 is a connecting-rod which is pivoted at its lower end to a lug on the inner side of the upper jaw J and pivoted at its upper end to a vertically-movable slide The latter is guided in ways on the standard G of the main frame and is raised and lowered by a cam k, which is secured to the shaft g and which is provided with a cam-groove receiving a pin or roller on the slide ks. Upon moving the slide 705 and connecting-rod lul downwardly the first part of this movement causes the rod to turn the upper clamping-jaw J outwardly from its position against the inner stop 7c3, as shown in dotted lines in Fig. 13, to its position against the outer stop k2, as shown in full lines in the same ligure. The upper jaw J remains in this outer position while being moved downwardly until the upper clamping-jaw reaches the end of its downward stroke and the upwardly -projecting flange has been bent on the blank. During the subsequent upward movement of the connecting-rod 7a the upper jaw J is first swung inwardly from the outer position against the outer stop k2 (shown in full lines, Fig. llt) to the inner position against the inner stop 7a3, as shown in dotted lines in the same Vligure, after which the Lipper jaw J remains in this inwardly-retracted position to the end of the upward stroke of the connectingrod 7a4. The slide 7c is iitted in its ways comparatively tight by means of a leather packing, so as to produce sul'iicient friction to resist the up- IOO ICS

IIO

ward-and-downward movement of the slide k until the upper clam ping-jaw j reaches the limit of its laterally-swinging movement.

The transverse movement of the slide I is produced by an elbow-lever L, which is pivoted to the carriage I and has its lower arm connected with the slide I, while its upper arm is connected by a rod Zwith ayerticallyreciprocating slide Z. The latter is guided in ways on the upper part of the standard G and is raised and lowered by a cam Z2, which is secured to the shaft g and which is provided with a cam-groove receiving a pinor rolleron the slide Z. The cam Z2 moves the slide inwardly in a positive manner; but the outward movement'of the slide is effected by a spring Z4, interposed between a depending lug on the slide andV an adjusting-screw on the carriage I', as shown in Figs. 13 to 15. The outward movement of the slide is adjusted by a screw Z2, arranged in adepending lug on the slide and engaging with the adjacent part of the carriage I.

For the purpose of adapting the machine for folding seam-hooks on the ends of the blanks of different widths the carriage I' is adjustable transversely in ways on the main frame, this adjustment being effected by an adjusting-screw Z6, journaled in the main frame and working in a screw-threaded opening in the carriage, as shown in Figs. 13'to 15. Upon adjusting the carriage I' each of the con necting-rods Z 104 is also lengthened or shortened, as may be necessary, by means of a turnbuckle Z7, which connects the twosec-y tions of the connecting-rod. After adjusting the carriage I the same is securely held in place by a clam pin g-screw Z8, passing through a horizontal slot Z9 in the standard of the carriage and enteringa screw-threaded opening in the standard of the main frame. The driving mechanism of the devices which form the seam-hooks 011 opposite ends of the blank are so timed that both upper clamping-jaws are moved downwardly at the same time toward the lowerelamping-jaws, respectively,and the opposite folding-jaws move inwardly and outwardly simultaneously. By this mechanism for folding the edges of the blank the same is securely held in place while being bent and the bending operation is effected by gradual and successive steps without stretching the metal and with the expenditure of a minimum amount of power.

M represents retaining-plates, whereby the blanks are held down upon the feed-table and con`veyer-belt while being carried from the tluxing wheels to the folding mechanism. These plates are arranged lengthwise over the central and side parts of the path of the blanks, and each plate is adjustably secured at its front end to the cross-bar d. After the seam hooks or flanges have been folded on the blank the latter is advanced another step or space by the primary conveyer and bends the blank into cylindrical form and seams the ends of the blank together. This forming mechanism is best shown in Figs. l, 2, 3, 5, 6, 7, and 16 to 22 and is constructed as follows:

N N represent the two sections of an expansi ble and contractible forming horn, around which the blank is bent into cylindrical form and upon which the ends of the blank are seamed or secured together. This horn is of substantially cylindrical form and arranged lengthwise over the central part of the feed-table in rear of the standard G. The division between the two sections ofthe horn is on one side of a vertical center` line through the h'orn, so that one section of the horn is which is connected with the rear end of the horn by a dovetail joint n, as shown in Figs.

7, 19, and 20. The movable section of the horn is pressed away from the stationary section by a spring n2, interposed between the horn-sections. the movable section may be limited in any suitable manner, the means for this purpose (shown in Figs. 6, 19, and 20) consisting of pins n2 n2, arranged on opposite ends of the movable section and engaging withvshoulders n4 n4 on the adjacent part of the standard G and the head N2. These stop devices limit the expanding movement of the movable section, which is produced by the pressure of the spring n2. The latter allows the movable section to close against the stationary section when the pressure of the spring is overcome. After the blank comes to rest under the horn the blank is clamped at its center against the under side of the stationary section of the This outward movement of g IOO IIO

ing-jaw, as shown in Fig. 3. The clampingjaw o is moved upwardly toward the horn by rotary cams o2, engaging with rollers 03 on the under side of the clamping-jaw o. The cams 02 are mounted on a horizontal arbor 04, which is arranged lengthwise below the clamping-jaw 0 and supported at its ends on brackets 05, which are secured to the adjacent part of the main frame, as shown in Figs. 3, 16, 17, and 18.

horn. Each of the forming-jaws is pivoted at its bifurcated inner end on the arbor 04.

P2 represents a vertically-reciprocating slide which is guided in ways on the brackets o5 and which is connected at its upper end by an oblique link p with the right-hand forming-jaw P. The left-hand forming-jaw P/ is yieldingly connected with the slide P2, so as to permit these parts to have a limited independent movement with reference to each other, the yielding connection for this purpose (shown in the drawings) consisting of an oblique link p, pivoted at its upper end to the jaw P and pivoted at its lower end to a follower 132; a guide-socket p2, arranged on the slide P2 and receiving said follower; a spring p", arranged in said socket and bearing with its upper end against the follower; a disk 795, bearing against the lower end of the spring p4, and an adjusting-screw p6, arranged in the bottom of the socket p2 and bearing against said disk. The cams 02 are secured to one of the forming-jaws, preferably to the arms of the jaw P, as shown in Figs. 3, 1G, 17, and 18. The upward movement of the follower p2 in the socket i's limited by a pin p7, arranged on the follower and projecting through a longitudinal slotps in the socket. The slide P2 is raised an d lowered by a rock-arm p9, which is connected by a link p10 with the slide, as shown in Fig. 3. The rock-arm p9 is connected with a horizontal rock-shaft p11, which is journaled trans- The rock-shaft is operated by a connecting-rod p12, connected at its lower end to a rock-arm p13 on the outer end of the rock-shaftlf)11 and provided at its upper end with a roller or projection which engages with a cam-groove in a cam p1, mounted on the shaft g. The latter is driven bya gear-pinion p15, mounted on a short shaft p16 and meshing with a gearwheel p12 on the shaft g, and a driving-belt passing around a driving-pulley p12 on the shaft p1, as represented in Figs. l and 8. Vhile the blank is being carried under the horn, the clamping-jaw o is depressed, the slide P2 is lowered, so that the forming-jaws stand below the path of the blank, and the follower p2 is moved upwardly in its highest position in the socket p2 by the spring p4. After the blank comes to rest under the horn the slide P2 is raised, whereby the formingjaws are moved upwardly toward opposite sides of the horn. During the first part of this upward movement of the forming-jaws the cams 02 are turned and operate the clamp, so that the central part of the blank is clamped against the under side of the horn, and during the remainder of the upward movement of the forming-jaws the latter engage with the ends of the blank and bend them around opposite sides of the horn, as represented in Fig. 17. The relative movement of the two forming-jaws is such that the left formingv jaw moves upwardly slightly in advance of the right forming-jaw. `This causes the left end of the blank having the downwardly or outwardly projecting hook to be bent around the horn in advance of the right-hand end of the blank, thereby permitting the upwardly or inwardly projecting hook on the right end of the blank to lap over the left hook Without interfering with the latter. When the slide P2 reaches the end ot its upward movement, the right forming-jaw has bent the right end of the blank its fullest extent around the adjacent side of the horn. Before the slide P2 reaches the end of its upward movement the left forming-jaw bends the left end of the blank around thevmovable section of the horn and moves the same against the stationary section, so that the further inward movement of the left forming-jaw is arrested, which causes the slide P2 upon completing its upward movement to slightly compress the spring p4. As the left part of the blank is bent around the horn the extreme outer end of this part of the blank lying bcyond the left formingjaw is caused to lie closely against the adjacent part of the horn and conform to the curved surface thereof by reason of the preliminary concave-convex bend e2, which has been formed in this part of the blank by the clamping-jaws E E, thereby permitting the hook on the right end of the blank to pass freely over the lelt hook. In the absence of the preliminary bend cS in the left end of the blank the latter would project tangentially from the horn when pressed against the same by the left formingjaw and prevent the right end of the blank from passing over the left end of the blank. The movable section ofthe horn stands normally in its expanded position and is pressed inwardly by the corresponding forming-jaw. The spring acting against the movable seetion opposes this inward movementand holds the section snugly against the blank and the latter snugly against the forming-jaw, whereby the blank is folded smoothly and evenly around the horn.

ln order to avoid any slack in the blank while bending it around the horn, which otherwise would interfere with the proper seeming of its edges, each 'forming-jaw is provided on the lower part of its face with yielding presser-pins q. Each of these pins is guided in the forming-jaw and pressed outwardly by a spring q', arranged in a socket q2 on the forming-jaw and bearing with one end against a screw q2, which closes the outer end of the socket, and bearing with its opposite end against ahead g4 on the inner end of the presser-pin, as shown in Fig. 22. In the retracted position of the forming-jaws the presser-pins are projected outwardly to their fullest extent, the movement of the pins in this direction being limited by their heads bearing against shoulders Q5 in the sockets. During the last portion of the upward and inward movement of the forming jaws the presser-pins bear yieldingly against the lower parts of the blank and press the same closely IOO IIO

the pins n3 of the movable horn-section .and

bearing-faces r on the opposing part of the stationary section of the horn. The slide R is guided in ways on the rear side of the standard G and is raised and lowered by a connecting-rod r, connected at its lower end to the slide R and at its upper end to a crank r2 on the shaft g, as shown in Fig. 3.

r3 represents a ham mer, whereby the hooks vof the blanks are seamed together and which is arranged lengthwise on the under side of the slide R. While the blank is fed underneath the horn and bent around the same, the slide is raised so that Ithe wedges and harnmer clear the horn, as shown in Figs. 16 and 19. After the blank has been formed around the horn the slide R' descends, and during the first part of this movement its wedges pass between the pins n3 and bearing-faces r of the horn-sections, as shown in Fig. 20, whereby the movable section of the horn is moved away from the stationary section, thereby interlocking the hooks of the blank and gaging the diameter of the can. After the horn and blank have been thus spread or expanded by the wedges the hammer presses the interlocked hooks of the blank downwardly against the top of the stationary horn and closes the hooks of the same together, as represented in Fig. 1S. Upon moving the movable hornsectiou laterally while expanding the horn the left forming-jaw is also moved outward the same extent as the movable horn-section. This movement of the left forming-jaw is perm itted while the slide P2 is still in its elevated position by reason of the yielding connection between the slide P2 and this jaw. The upper side ofthe stationary horn-section is preferablyprovided with a longitudinal groove r4, which receives the seamed part of the blank and causes the rib or bead which is produced on this part of the blank by the several thicknesses of metal to project inwardly from the blank, leaving the outer side smooth and cylindrical. After the blank has been thus seamed thc slide R', carrying the hammer and wedges, is raised and the slide P2 is lowered, so as to retract the forming-jaws below the path of the blanks, thereby leaving the sealned blank free to be removed from the horn and permitting another unseamed blank to be fed under the horn. If the pivot of the horn becomes worn more unevenly, the can-body formed from the blank on the horn while in this condition is liable to have a conical shape, which would interfere with the application of the heads to the ends of the can-body. In order to avoid this conical formation of the can-body, the wedges R are adjustable transversely on the slide, which permits the wedges to be adjusted, so that one end of the movable horn-sections is vshifted outwardly more than the other asufcient extent to preserve the cylindrical form of the horn and the can-body formed on the same. As shown in the drawings, Figs. 3, 5, 19, and 20, each wedge is provided with a horizontal guide-rib T5, which engages in a horizontal guide-groove in the adjacent end of the slide R', and the Wedge is adjusted transverselyv by a screw r6, journaled on said slide and working in an internally-screw-threaded Vear on the wedge. After adjustment the wedge is held in position by a clamping-screw fr passing through a horizontal slot in the wedge and entering a screw-threaded opening in the slide R.

S S represent two front gages which'are engaged by the front edge of the blank as the latter comesto rest under the forminghorn and whereby the blank is squared or alined with reference to the forming vhorn and jaws. These gages are arranged on opposite sides of the rear part of the horn and in the path of the unformed blank and are secured to a transverse rock-shaft s, which is journaled on the mainframe below the feed-table, as shown in Figs. l, 2, 5, and 6. This shaft is turned in a direction for moving the gages forward by a spring s, interposed between an arm s2 on the rock-shaft .s and the adjacent part of the frame. The forward movement of the front gages is limited by stops S3, which may be formed by rearward extensions of the sideguides c. As the blank is carried from the folding mechanism to the forming mechanism the front edge ofthe blank engages with the front gages. If one side of the blank moves slightly in advance of the other side, the advancing side strikes the front gage on its respective side first and is held back until the other side of the blankv also reaches its gage, thereby alining the blank preparatory to bending thev same around the forming-horn. If the blanks are moved farther than the normal position of the front gages, thelatter yield against the pressure of the spring s', and when the ends of the blanks are bent upwardly away from the gages and around the horn the gages are returned to their normal position by the spring.

After the blank has been formed into a cylindrical can-body and seamed on the forming-,horn the can is removed rearwardly from the horn and moved forward another space by an auxiliary feed wing or finger b, which engages with the rear edge of the tubular can-body, near the lower side thereof, and passes through a longitudinal groove 67 in the stationary section of the forming-horn.

One of these auxiliary feed-wings is secured to the right-hand conveyer-beit in line with each main feed-wing of this belt. V'Vhile the can-body is being removed from the forminghorn, the movable section of the latter is held in its expanded position by the spring n2, thereby centering the can-body and holding the same against moving laterally, whereby the can-body is prevented from catching against any shoulders on the head N2 or other adjacent parts of the machine.

In order to disengage the main feed-wings from the rear edge of the blank after the latter has been carried underneath the forminghorn, and thereby prevent the blank from being kinked when subsequently raised by the formin gj aws, the primary conveyer-helts are moved slightly backward after each intermittent forward movement of the belts. The driving mechanism for producing this movement of the belt is constructed as follows:

T represents a star-wheel secured to the inner end of the shaft b3 of the delivery sprocket-wheel h and provided with teeth t, which are separated by radial slots 2'/ and each of which is provided in its outer end with a concave recess or seat t2.

T represents a horizontal shaft which is journaled transversely in the frame above the star-wheel and which makes one rotation in the direction of the arrow, Fig. l0, for each intermittent forward movement of the primary conveyer.

t3 represents a rotary crank-arm secured to the inner end of the shaft T and provided with a crank-pin t, which is adapted to engage successively with the teeth of the starwheel and turn the latter one space or step at a time. The hub of the crank-arm is provided on its periphery with a recess t5 on the same side of the center on which the crankpint4 is arranged; a low concentric face 156, arranged in rear of said recess; an outwardlytrending cam t7, arranged at the rear end of the low concentric face, and a high concentric face ts, extending from the cam t7 to the front sideof said recess. While the folding and forming mechanisms are operating upon blanks the primary conveyer-belts are standing still, and during this time the high concentric part S of the crank-hub engages with the concave recess of one tooth of the starwheel, as shown in Fig. l0, and locks the same and the belts connected therewith against movementin either direction. After the folding and forming operations have been completed and the blanks are ready to advance another step or space the recess t5 of the crankhub is presented to the operative tooth of the star-wheel and unlocks the same, and the crank-pin t4 engages with the front side of the operative tooth and turns the star-wheel in the direction of'the arrow until the crankpin clears the tooth, as represented in Fig. l1. The distance which the crank moves the star-wheel while in engagement with a tooth of the same is more than one space; but this movement of the star-wheel is limited by the next following tooth engaging with the low concentric part t of the crank-hub, as shown in Fig. ll. As the crank-pin leaves the starwheel the cam 'L7 on the crank-hub engages with the trailing part of the next following tooth of the star-wheel and turns the latter backwardly or in the direction opposite to the arrow until the high concentric part t8 of the crank-hub engages with the concave face of the respective tooth, as shown in Fig. 12. As the crank-hub continues its movement in this direction its high concentric face t8 bears fully against tbe concave face of the operative tooth, as shown in Fig. l0, thereby locking the star-wheel against turning until the crank-pin engages with the opposite side of the operative tooth of the star-wheel. By this means of driving the primary conveyerbelts the latter move the blank forward to the desired place and then back up slightly,where by the wings of the belts are disengaged from the rear edge of the blank and the latter is left perfectly free to be operated upon. This is particularly desirable in the forming mechanism, in which the blank is liable to be kinked if its rear edge remains in engagement with the main feed-wings of the belts when the forming-jaws bend the blank around the forming-horn. During the first part of the rearward movement of the crank-pin t4, while in engagement with a tooth of the starwheel, the crank-pin slides from the outer end of the tooth toward the inner end or base thereof, and during the last part of the rearward movement of the crank-pin, while in engagement with the tooth, the crank-pin slides from the inner end or base of the tooth toward the outer end thereof. By this means the point of contact between the crank-pin and the star-wheel gradually approaches the pivot of the star-wheel during the first part of its movement while in engagement with the star-wheel tooth, and during the last part of this movement of the crank-pin the point of contact between the crank-pin and starwheel gradually recedes from the pivot of the star-wheel, whereby the primary conveyer is started easily and slowly and is moved forwardly with a grad ually-increasing speed during the first part of the stroke and with a gradually-decreasing speed during the last part of the stroke, thereby avoiding displacement of the blanks and also avoiding undue wear upon the machine. Furthermore, this means of driving the primary conveyer permits of driving the machine faster, thereby increasing the capacity of the same without danger of displacing the blanks, which would be the case if the movement of the blanks werestartedandstoppedsnddenly. Theshaft T is driven from the shaft g byintermeshing bevel gear-wheels t, secured to the shaft'l", and a longitudinal shaft 2510 and an upright shaft tu, connected at its upper end by apair of bevel-gears t12 with the shaft g and at its IOO IIO

lower end with the longitudinal shaft z510 by a pair of bevel-gears 1513.

After the can-body has been removed from the forming-horn the same is presented to the soldering devices, whereby the same is hermetically sealed and which is constructed as follows:

U represents the soldering-horn or internal guide which supports the cans during the operation of soldering the seams thereof. This horn is arranged lengthwise in the rear of the forming-horn and consists of a n umher of longitudinal guide-bars u, which are connected at intervals by cross-heads u'. The uppermost bar u of the soldering-horn supports the cans on their upper inner side and is provided with a longitudinal groove which receives the seam rib or bead on the inner side of the can. 'Ihe front ends of the bars forming the soldering-horn are connected with the head N2 on the rear end of the forming-horn, and its lreal-most cross-head u is provided on its under side with a supporting-roller u2, which runs on the top of a supporting-wheel n3. The latter is secured to a transverse shaft u4,which is journaled in the lower part ofthe main frame and which is turned in the direction of the arrow, Fig. 27, by a chain belt a5, passing around sprocket-wheels 1,06 20', secured to the shafts T and u, respectively, as shown in Figs. 23 and 24.

asus represent two longitudinal side guides, which are secured tov the main frame and which support the cans on opposite sides below the center while the can-bodies are moved past the soldering devices. As the can-bodies move rearwardly from the forming-horn they pass upon the front end of the soldering-horn.

a9 represent-s a continuously-moving chain belt which has feed-wings uw and constitutes the secondary con-veyer, whereby the canbodies are moved lengthwise over the soldering-horn and past the soldering devices. This belt is arranged with its rearwardly-moving operative portion lengthwise on the left side of the soldering-horn and passes around receivin g and delivery sprocket-wheels u M12. The delivery sprocket-wheel M12 is journaled on an upright stud on the frame and the rethe folding or forming mechanism which necessit-ates stopping the machine to put the machine in order. If the can-bodies were permitted to remain for a considerable length of time under the soldering device while the machine is so stopped, the can-bodies are llable to be burned. In order to avoid this,the receiving sprocketwheel un is connected with its driving-shaft 'w13 by a clutch, which compels the sprocket-wheel to move forwardly with the shaft, but permits the sprocketwheel to move `forwardly independently of the shaft. veyer to be operated by hand independent of its driving mechanism when the folding and forming mechanisms are clogged, thereby enabling the can-bodies which are-underneath the soldering device to be cleared out. The clutch for this purpose (shown in the drawings, Figs. 25 and 26) consists of a spring catch or pawl um, pivoted on the receiving sprocketwheel un and engaging with the front side of a driving-lng ulg on the side of the upright shaft uw. During the forward movement of this shaft its lng engages the clutch-pawl and drives the receiving sprocketwheel and conveyer-belt running around the same forward; but when the sprocket-wheel is turned forward independently of the shaft the pawl trips over the lug without affecting the shaft. The sprocket-wheel is preferably provided with a crank-wheel uw for turning the same.

As the can-bodies are carried rearwardly along the soldering-horn the seam thereof is first moved past a soldering device, which applies solder to the same and which is constructed as follows:

V represents a soldering roller or steel arranged lengthwise over the front part of the soldering-horn and adapted to apply solder to the outer side of the seam on thev upper side of the can-body. The-solder for this purpose is supplied from a solder-melting pot o, which is arranged in rear of the Solder-- ing-horn and from which the solder is carried to the soldering-roller byafeed-roller o', immex-sed with its lower part in the molten solder in the pot,and an intermediate or transfer roller o2, which runs `in contactl with the upper part of the feed-roller and solderingroller and transfers the solder from the feedroller to the soldering-roller. The solderfeed roller is mounted on a longitudinal shaft fus, which is journaled in bearings on the main frame and which is turned constantly in the direction of the arrow, Fig. 30, by a chain belt 1:4, passing around sprocket-wheels fui Q16, secured, respectively, to the shafts tlf Q13. The soldering-roller and transfer-roller are secured to shafts v7 08, which are journaled with their ends in rock-arms v9 o9 and are driven by atrain of intermeshinggear-wheels 0107111 012, secured, respectively, to the front This permits the secondary con- LOD IIO

ends of the shafts 'U3 '118117, as shown in Figs. f

24, 27, and 30. The rock-arms are pivoted at their inner ends on the shaft U3 of the solderfeed roller and rest at theirfront ends on Vertical adjusting-screws U13 U13, arranged on the adjacent part ofthe frame. the melting-pot is kept in a molten state by one or more burners '014, arranged below the The solder in Y against the inner side of the rollers 'c7178. The screws U13 are so adjusted that the lowermost part of the soldering roller or steel is separated from the uppermost guide-bar u of the soldering-horn by a space which is less than the thickness of the seam of the can body. As the can-body moves rearwardly along the solderinghorn the seam of the can-body moves between the horn and the soldering-roller and lifts the latter slightly. The front edge of the peripheryof the solder ing-roller is rounded to facilitate the passing of the can-body underneath the same. As the. can-body passes the underside of the soldering-roller the latter while retating in contact with the same applies solder to the same. The distance between the can-bodies as the same are fed along the soldering-horn is less than the length of the soldering-roller, so that the latter passes from one can-body to another without dropping to its lowest position except when the operator misses feeding a blank. As the transfer and solderingrollers rise and fall the driving gear-wheels o U12 are unaffected, because the arms o9, supporting the saine, swing concentrically with the solder-feed roller o. This construction of soldering device insures a uniform application of solder along the entire length of the seam and eects a saving in the use of solder over the former method, in which a quantity of solder was applied at the front end of the seam and spread lengthwise toward the other end of the seam. Fresh solder is introduced into the melting-pot to make up for the solder which is removed by the feed-roller. This solder is preferably supplied in the form of wire, which is unwound from a reel and passes over a curved guide nl, thence downwardly through an oblique guide o, and into the melting-pot, as shown in Fig. 3l. The solder-wire is fed forward intermittently by a gripper, which has a forward and backward movement and which grasps the solder-wire during its forward movement, but releases the solder-wire during its backward movement. This gripper consists of a lower jawn, fixed on a rockarln 'U19 and engaging with the under side of the solder-wire, and a movable upper jaw 1:20, which is pivoted on the rock-arm and held in engagement with the upper side of the solder-wire by a weight U21. The rock-arm 'U19 is secured to a rock-shaft @22, which is operated by a connecting-rod w23, connected at one end with a crank @24 on the sprocket- Wheel tw, and connected at its otherend to an arm 1:25 on the rock-shaft 1122, as shown in Figs. 24 and 30. The solder-wire is prevented from moving backward with the gripper by a spring-catch c2, pivoted on the guide n and engaging with the solder-wire in the same, as shown in Fig. 32. When it is desired to stop the feed of solderwire into the melting-pot, the movable jaw of the feedgripper is thrown backward against a stop U27, as shown in dotted lines in Fig. 30, in

which position the gripper isinoperative and the arm carrying the saine moves back and forth idly.

After the can-bodies have been carried past the soldering roller or steel the same are carried past the under side ot' a burner W. The burner is arranged lengthwise over the path of the can-bodies and its flame is directed downwardly against the seam of the can-body, whereby the solder on the salue is lthoroughly melted and caused to soak or creep into the crevices of the seam, thereby insuring sealing thesamehermctically. Asthecan-bodies move along the rear part of the solderinghorn the lower parts of the can-bodies pass between the rollers u2 uf. After the canbodies leave the rear end of the soldering horn they are guided and supported by the side guide bars or rails us, which extend be youd the rear end of the soldering-horn, and by a bottom guide-rail fr, which extends rearwardly from the soldering-horn and supports the can-bodies on the underside, as shown in Figs. 27 and 29.

The surplus solder is removed from the top or outer side of the seam by a wiper or brush x', of asbestos or similar material. This wiper is arranged obliquely in the path of the upper part of the can-bodies, and as the cans pass underneath the same the surplus solder is wiped off from the seam and discharged from one side of the can-body. The wiper may be supported in any suitable way-for instance, by means of a bracket rc2, secured to the main frame. By arranging the wiper iu rear of the soldering-horn the solder which is wiped off from the can-bodies is not deposited on the uppermost rail of the solderinghorn, where it would accumulate and interfere with the passage of the cau-bodies. By arranging the wiper obliquely the solder is carried laterally from the cau-body and prevented from accumulating on the wiper and being deposited in a lump on one of the caubodies when the solder cools and hardens.

When the rear end of a canbody reaches the wiper, the pressure of the latter upon this end of the body is liable to tip up the front end of the can-body and displace the same. n order to avoid this, a longitudinal retaining-bar m3 is provided, which is adapted to bear against the inner lower side of the canbody and hold the saine down in its normal horizontal position while the operator is operating upon the can-body. This retainingbar is secured to the lower rear part of the soldering-horn, as shown in Fig. 27. After the surplus solder has been wiped from the seam of the can-body the latter is carried with its seam underneath a perforated airpipe y, whereby jets of air are delivered against the seam and the solder on the same is cooled. After passing the cooling device the can-bodies are discharged by the secondary conveyer-belt from the tail end of the machine.
